When he saw the letter, Wang Yi felt that one head was two big.

Like cheating, he hurriedly ran out early on Monday morning, just so as not to be bumped into by Mu Xiwen. As a result, it was true that they didn't bump into each other, and they came to leave a letter for themselves.

Seeing Wang Yi frowning, as a ring spirit who knew the whole process, he was gloating and sitting on the computer desk watching the play, and he was waiting for the melon seeds.

Forget it, think about it tomorrow.

After sorting out his belongings, Wang Yi put on his schoolbag and appeared directly at the Xingwang Inn.

It was already past 7 o'clock in the morning, and the attack of the ghost clan had ended 2 hours earlier. Although the streets were not bustling at this time, the crisis caused by the war was unprecedentedly high, and the purchase of food by ordinary people added a bit of false prosperity to the neighborhood.

Passing through Xingwang Street, Wang Yi walked into the Changfeng Inn and knocked on the door of Huayao. Without saying a few words, Wang Yi shocked Huayao.

"You said, you want to exchange a first-grade Danfang for the first volume of my "Hundred Veins Silver Needle"?"

Wang Yi nodded and said, "That's right." ”

Since learning about the history of Chinese medicine, Wang Yi has been fascinated by "Hundred Veins Silver Needle" for a long time, and his illness was cured by Chinese medicine, Wang Yi's confidence in "Hundred Veins Silver Needle" is unprecedentedly high.

"Hundred Veins Silver Needle" is the supporting secret method of the Chinese medicine major exercise "Void Spirit Hundred Pulses", "Void Spirit Hundred Pulses" was already very famous in the middle of the Tai Gu Dynasty, but the reason why he became famous was not because of how powerful this set of exercises was, but because of the powerful effect of the supporting secret method "Hundred Veins Silver Needle" to cure all diseases.

It stands to reason that such a powerful secret method, even if Hua Yao has not yet become a medical immortal, he also knows the value of the secret method, and he will not have the idea of exchanging at all, not to mention that Wang Yi only provides a pill for a first-grade pill.

However, after Wang Yi read through the part of the "Taigu General History" about Chinese medicine, he consulted many classics dedicated to Chinese medicine, and finally found that the first volume of this "Hundred Veins and Silver Needles" was actually very likely to be traded.

First of all, in terms of value, in the primeval period, the things that were really valuable must be things related to immortal cultivators.

"Hundred Veins Silver Needle" is known as the living dead, flesh and bones, and can solve the injury and illness problems of the vast majority of immortal cultivators. But the part that really works for immortal cultivators actually starts from the second volume.

The first volume of "Hundred Veins and Silver Needles", due to the low cultivation foundation, his scope of application can actually only be aimed at ordinary people. Although Wang Yi had a cultivation foundation before, he is also an ordinary person with no cultivation now.

Of course, it is a merit to treat people, but it can only be used for ordinary people, and there is no advantage in value. It is used to exchange for a Dan prescription that was most scarce in the primeval period, although it cannot be said to be a sure profit, but it will not be lost.

Secondly, Wang Yi had studied the Hua family and knew that their main cultivation method "Void Spirit Hundred Veins" had a saying that it was not spread to the outside world, but there was no corresponding restriction on the secret method.

Not only the "Hundred Veins of Void Spirits", but throughout the primeval stage, and even in later generations, people did not have too many restrictions on the inheritance of secret methods.

There's a reason for that.

The reason why it is called a supporting secret method is because most of the conditions for the use of the secret method are closely related to the exercises of the major. In other words, if you don't practice the "Hundred Veins of Void Spirit" and condense the special true qi attribute of "Hundred Veins of Void Spirit", even if you learn the "Hundred Veins Silver Needle", you will actually not be able to use it.

It's like, you have a mountain of cultivation, but this microwave oven needs to be powered by 220V, but you can't generate electricity.

From ancient times to the present, almost all of the supporting secret methods have this kind of restriction. Therefore, if the Immortal Cultivator Family wants to prohibit the spread of the exercises, they only need to restrict the major exercises.

"Wang Xiaoyou, you may have something unclear. Hua Yao smiled, obviously not angry because Wang Yi wanted to change his secret method, "If you don't cultivate the Hundred Veins of the Void Spirit, even if the Silver Needle of the Hundred Veins is given to you, you will not be able to use it." And this "Hundred Veins of Void Spirits" is an unpassed secret of our Hua family. ”

Of course, Wang Yi understood, but he said indifferently: "Yao Lao, I know what you said, I just want to try whether it is possible for me to learn the "Hundred Veins Silver Needle" in this situation. If you learn it, it's naturally good, and if you can't learn it, it's okay, anyway, this condensing pill is given to you, and it will only play a greater role, and I won't have anything to lose. ”

Indeed, Wang Yi only gave the pill to Hua Yao, not that he couldn't refine the condensation qi himself. From this point of view, Wang Yi really has nothing to lose.

On the other hand, Hua Yao actually didn't lose anything, but just said the secret method, and it was just a big deal that one more person could treat ordinary people. And this hope, in fact, is also very slim.

However, compared with himself, Hua Yao felt from the bottom of his heart that Wang Yi was a loss.

Not to mention that Wang Yi can't learn this set of acupuncture methods, even if he learns it, it can't be mass-produced, and it will take more time to treat people. But the Dan Fang is different, its own unique Dan Fang, the income of the spirit stones produced is very huge.

Why, for example:

There are 11 kinds of herbs in Ningqi San, the medicinal properties are strong and weak, the year is about 10 years, and a large number of purchases are actually not very valuable, but a herb called 'Bailu' is worth a lot of money, a 10-year-old plant, you can sell it for the price of 1 piece of 1 spirit stone.

And all the remaining herbs combined, the value is only about one-tenth of the 'white dew'.

This is not to say that 'white dew' is the most valuable of the 11 herbs, on the contrary, it is just an adjuvant. The reason why it is so expensive is because there are two other 1 pins of Dan prescriptions, and 'white dew' appears at the same time, which makes the value of herbs rise.

Supply and demand determine prices, and this was also true in ancient times.

If Wang Yi had a unique Dan prescription, the price of a large number of herbs would be purchased at a very low cost. And if there is competition, then the price of raw materials will naturally rise accordingly.

And Huayao's "Hundred Veins Silver Needle" does not have the same trouble.

Huayao thinks that Wang Yi has lost money, but Wang Yi actually doesn't value this. This condensing pill was purchased by Wang Yi today in Kunlun Mountain Traditional Chinese Medicine Park, and the price was 1 piece of 1 spirit stone. As for why Kunlun Mountain Traditional Chinese Medicine Park has Danfang reserves, it is because of the background of Kunlun commerce and trade, which is Kunlun Immortal Sect.

——One of the few remaining sects of immortal cultivation in the present world.

This price is something that Hua Yao could never dream of, not to mention 1 piece of 1 spirit stone, the Danfang of the primeval period, in fact, it will almost not be sold.

The reason is that, as I just said, the value of the unique Danfang is much greater than the proceeds from the sale of the Danfang.

But the era in which Wang Yi lived was tens of thousands of years ago. Danfang, which no longer wants to spread, will also be passed on to the next generation because of the dying of people. One child is fine, but if you have two sons, can you pass on only the eldest son and not the second son? Obviously, many people can't do that.

In this way, it has been passed down from generation to generation, and it is actually difficult to calculate how many people will master a Danfang.

However, even if it is a pill that is mastered by many people, it is still very valuable in this world. And the reason why Wang Yi's condensation is so worthless is because the 6 Chinese herbal medicines, including the main one, were out of print in the present world a long time ago.

The word out of print, Wang Yi likes it very much!
